    Measuring converters are often used in the information-measuring system for transmitting information to the input of high-speed digital oscilloscope (for recording and analysis of emergency operation), do not require an additional power supply.
    In the devices is a function of galvanic isolation between the input and output circuits for each channel, as well as any link between the chains and the chains of the other channels.

    Measuring range input: 0-5A, 0-400V.
    Measuring range Output: 0-5, 0-5 -6.5, 0-5 , 100 mA.
